title: Cognitive and emotional dysfunction in mild cognitive impairment.
abstract: Although mild cognitive impairment (MCI) is a widely accepted construct both clinically and in the research literature, it remains a heterogeneous condition that varies in presentation and prognosis. This article first reviews the evolution of the diagnosis of MCI, followed by examination of pros and cons of cognitive assessments commonly used to assess for MCI. Emotional changes commonly seen in MCI are also reviewed. Finally, the relation between cognitive and emotional dysfunction is examined, including a discussion of specific psychological symptoms seen in subtypes of MCI, and how the presence of neuropsychiatric symptoms may affect the risk for progression to dementia.
